I ran the code in the following article https://www.mql5.com/en/articles/112 to understand the concept of magic numers . I ran the code magic_exp0_en.mq5. Whie debugging I tried to switch the focus of the current chart between two different time frames i.e. EURUSD M5 and EURUSD H1 to see if this would cause an error in position opening but the code always focuses on only one of the charts.
Basically the question would be what settings I need to make to run one EA over one currency pair with two different timeframes so I can replicate the authors tests on his article
